I want to do bandwidth shaping using dummynet. I want the box to act as a bridge only and no layer-3 filtering. To that effect, I have the following parameters in /etc/sysctl.conf:
net.link.ether.bridge_cfg=ed0,rl0 net.link.ether.bridge=1 net.link.ether.bridge_ipfw=1 net.link.ether.ipfw=1 net.inet.ip.fw.one_pass=1 net.inet.ip.fw.enable=0
My first question is that does this ensure that packets are processed at the bridge level and not at layer-3? I am a bit confused between these two parameters: net.link.ether.bridge_ipfw, and net.link.ether.ipfw
What is the effect of each specifically?
Two is that I am trying to allocate different bandwidth limits for: 1. Internet to home-network-A (in and out) - 128Kbps 2. Home-network-B to Home-Network-A (in and out) - 1Mbps
So I do: ipfw -f flush ipfw add pipe 1 ip from any to Network-A ipfw add pipe 2 ip from Network-B to Network-A ipfw pipe 1 config bw 128Kbit/s queue 10 ipfw pipe 2 config bw 1000Kbit/s queue 10
But I find that the effective limit is 128Kbps only for all transfers!! Why isn't the traffic between Network-A and B put in pipe-2?
Also, if someone can point me to a document with lots of examples of dummynet usage. I found Luigi Rizzo's page a bit lacking examples of various scenarios.
